Final Fantasy Hacktics

I was wondering how I could do this. I'm pretty sure I could do it with FFTEdit but the save I want to edit isn't in the first slot of the memcard. I already have the save file converted, I just want to change his sprite to something interesting. Maybe like a female geomancer sprite?(which might not be possible without changing his gender)

Since I have almost no idea what I'm doing, please help me.
